This raises an interesting point.

In looking at UserString.py, it's clear that the author of that module
/intended/ UserString instances to look like regular strings (__str__,
__rep__, etc. all return self.data).

Perhaps this string-look-alike behaviour breaks with builtin functions,
because they subvert the special class methods.
